中文摘要:
      连续碳纤维增强复合材料具有轻质高强等优异性能,结合3D打印技术在船舶制造行业具有广阔应用前景,其中丝材制备是目前急需解决的关键技术。所以采用正交实验法,以树脂进给量、外包裹结构件加热温度、收卷速度三个丝材制备工艺参数为研究因素,考虑丝材制备工艺参数之间的交互作用,根据正交实验表进行连续碳纤维增强聚碳酸酯复合材料丝材制备实验,以碳纤维丝材的单位直径、拉伸强度性能为衡量指标。通过极差分析和方差分析,确定了制备连续碳纤维增强聚碳酸酯基体丝材整体性能达到最优的工艺参数组合为:树脂进给量为33.3mm3/min、外包裹结构件加热温度为270℃、收卷速度为150mm/min;最优工艺参数下制备的丝材直径为0.594mm,拉伸强度达最大为451.07MPa。研究结果可为连续碳纤维增强复合材料在船舶建造领域的应用奠定基础。
英文摘要:
      Continuous carbon fiber reinforced composites have excellent properties such as light weight and high strength. Combined with 3D printing technology, they have broad application prospects in the shipbuilding industry, among which wire preparation is the key technology urgently needed to be solved. Therefore, orthogonal experiment method was adopted, taking resin feed rate, heating temperature of outer wrapped structural parts and winding speed as the research factors, and considering the interaction between the process parameters of wire preparation, the preparation experiment of continuous carbon fiber reinforced polycarbonate composite was conducted according to the orthogonal experiment table, and the unit diameter and tensile strength properties of the wire were measured. By range analysis and variance analysis, the optimum process parameters were determined as follows: resin feed rate of 33.3mm3/min, heating temperature of the wrapped structural parts of 270℃ and winding speed of 150mm/min. Under the optimal process parameters, the diameter of the prepared wire is 0.594mm, and the tensile strength is up to 451.07MPa. The research results can lay a foundation for the application of continuous carbon fiber reinforced composites in ship construction.
